Picasso, in his abstract art, painted only the essential elements of his subject matter. Business proposals and other writings often carry abstracts, or summarizations, of their contents. In this vein, object-oriented programming preaches abstraction: the elimination of the extraneous and the retention of only the necessary. For example, if you’re developing management software for veterinarians, you’ll create a Dog class (derived from a Pet class) that contains pertinent data about dogs. This Dog class represents an abstraction of real-life dogs, in that it doesn’t model a dog exactly; it only models the aspects of dogs necessary for the software. For example, you wouldn’t include a chew (Shoe shoe) method or a lickEmbarrassingly() method because your software has no need to model these dog actions. Distilling an object to the minimum representation required reduces complexity, accelerates development, and slashes defects.
